[CI ][Misc] Add timeout check for custom op CI and optimize test parameters (#8755)

### What this PR does / why we need it?

This PR introduces a mechanism to track test duration in `conftest.py`
and skip subsequent tests in a file if a certain number of tests exceed
a timeout threshold. This is intended to prevent CI hangs or
long-running nightly tests. Additionally, it reduces the parameter space
for `test_fused_qkvzba_split_reshape_cat.py` to further optimize CI
runtime.

### Does this PR introduce _any_ user-facing change?

no

### How was this patch tested?

nightly
